This question already has an answer here:
As we know Hogwarts and its surrounding environment are located in Great Britain and so wizards and witches speak British English. But we see students from various ethnicities at Hogwarts, which means wizarding is present all over world.
Now in the real world there are different words for same object depending upon British English and American English like football/soccer, cab/taxi and many more...
Does this affect the wizarding world, especially spells?
For example, does “Avada Kedavara” change in America?
